通过对民勤退化梭梭进行滴灌灌溉,结果显示：在滴灌灌溉1个月后,梭梭土壤水分在10 cm 以下变化较大,50 cm达到最大值后慢慢减小,130 cm与对照区恢复一致；当年新梢最大生长量平均增加11.5 cm,平均生长量增加4.5 cm,滴灌区与雨养区差异极显著(P<0.01)；滴灌区土壤平均含水量与梭梭新梢最大生长量相关性较高(R2=0.987),而雨养区土壤平均含水量与新梢最大生长量相关性较低(R2=0.275)。滴灌灌溉对退化梭梭的恢复具有重要作用,能够增大生长量,提高植被盖度,节约水资源。

The drip irrigation was conducted on degenerated Haloxylon ammodendron in Minqin oasis.Result shows that a month after drip irrigation,soil moisture at 10 cm below Haloxylonammodendron changes significant-ly;soil moisture at 50 cm decreases slowly after reaching a maximum;soil moisture at 130 cm is consistent with that of CK.The maximum growth of the shoot in the very year averagely increase 1 1 .5 cm.The average growth increase 4.5 cm.Drip irrigation district and rain-feed area have very significant differences (P <0.01).The mean moisture content of the soil irrigation district’s and the largest growth of Haloxylon ammodendron have higher correlation (R2= 0.987).The mean moisture content of the soil in rain-feed area and the largest growth of new shoots have low correlation (R2 = 0.275).Drip irrigation has an important role on degenerating recovery,can increase the growth,can improve the vegetation cover,and conserve water resources.
